His observations, which he reported to the Royal Society of London, are among the first descriptions of microbes(微生物).Leeuwenhoek discovered an entire universe invisible to the human eye.He found different microbes in samples of pond water, rainwater, and human blood.He gave the first description of red blood cells, observed plant tissue,examined muscle,and investigated the life cycle of insects. Nearly two hundred years later, Leeuwenhoek’s discovery of microbes helped French chemist and biologist Louis Pasteur to develop his “theory of disease”.This concept suggested that disease originates from tiny organisms attacking and weakening the body.Pasteur’s theory later helped doctors to fight infectious diseases including anthrax, diphtheria, polio, smallpox ,tetanus, and typhoid.All these breakthro
